1. Process for the manufacture of mixtures of acetic acid, acetaldehyde, ethanol and olefins having two to four carbon atoms in a 1 : 1 et 2.5 : 1 molar ratio of the said oxygen-containing compounds to the olefins, by reacting carbon monoxide and hydrogen in the presence of catalysts containing rhodium and, if appropriate, promoters, in the gas phase at temperatures between 150 and 3508C and under pressures between 1 and 300 bars, characterized in that the catalysts contain 0.1 to 5.0 % by weight of sodium or potassium which are applied by impregnation with corresponding oxides, hydroxides, salts or complex compounds with the exception of double salts or rhodium or magnesium with sodium or potassium halides and of potassium rhodium cluster complexes. |
